How do you replace the transmission modulator valve on a 1985 380sl Mercedes Benz?

The modulator valve is located on the LH side of the tranny and has a vacuum line going to. After replacing you have to set the modulator pressure by connecting a gauge to the tranny, removing the cover from the modulator valve and turning adjustment bar underneath. With out pictures its hard to show how the gauge is connected. To be quite honest if you really have done the tests required to diagnose the modulator than setting the pressure should be the easy. If you have more specific questions feel free to add answers and I will do my best to help. Sorry my answer could not be more complete.

What causes a Ford Aerostar XLT not to shift into overdrive and stay in third gear no matter what speed you go?

my 93 aerostar did this, my problem ended up being the modulator valve on the transmission, a 13.00 dollar part at autozone, it was sucking tranny fluid into the motor, wouldn't shift right and was running terrible. you can tell if this part is bad by simply getting under the van, find the transmission pan, on the passenger side, on the pan lip(hard to see on a 93) there is a small hose connected to it, pull it off, if tranny fluid is in that hose valve is bad Another possibility is that the torque converter is bad.
